||The effects of cement dust exposure on acute respiratory health were assessed among 51 male workers of a cement plant in Tanzania with high exposure and 33 with low exposure. Data on respiratory symptoms were collected during interviews using a structured questionnaire. Peak expiratory flow (PEF) was measured pre-shift and post-shift for each worker. Exposures to respirable and total dust levels were determined from personal sampling. Compared to low exposed workers, high exposed workers had more acute cough, shortness of breath and stuffy nose, and their mean percentage cross-shift decrease in PEF was significantly more pronounced. An exposure-response relationship was found between respirable dust and percentage cross-shift decrease in PEF. Respirable dust exposure ≥2.0mg/m3 versus <2.0mg/m3 was associated with increased prevalence ratio for cough (7.9) and shortness of breath (4.2).
